chines, of which the following is a specification, reference being had therein to the accompanying drawings.

In the manufacture of boots and shoes, after the upper has been secured to the sole by stitching, the sole and seam are leveled by hammering and rubbing. This process is known as beating out. When performed by hand, as is commonly done, this operation requires the exercise of considerable physical strength, and is an exhausting operation for the workman.

My invention has for its object to provide a machine by the employment of which the beating out may be performed more effectively, easily and quickly than it is at present performed so far as known to me.

The invention is not an automatic machine of the class which furnishes the power to do the beating out. In employing my invention the workman may still move and guide the beating-out tool by hand while he also applies and controlsthe required pressure transmitted through the tool to the work. In the embodiment of invention herein shown and described this latter is effected by means of a treadle operated by the foot of the operator. Byusing my invention, the operator is relieved of the fatigue of pressing the tool upon the work, but is still enabled to move and guide it, thus combining the advantages of the hand tool and the automatic machine.

The invention,vembodied in the best form known to me, is fully set forth in the following description, taken in connection with the accompanying drawings, and the novel features thereof are pointed out and clearly defined in thev claims at the close of this specification.

In the drawings, Figure l is a side elevation of a machine embodying my invention, the head being shown in section for greater clearness. Fig. 2 is a front elevation. Fig. 3 is a front elevation, and Fig. 4 an end elevation of a modification of the device showing means for applying power to operate the beating out tool to obtain the slight reciprocation of the tool which is desirable in con- I nection with the larger movements imparted by hand by the operator. Fig. 5 is a longitudinal viewv of the beating out tool showing the details thereof. Fig. 6 is an end view of the same. Fig. 7 is a view showing the manner in which the handle rods of the said beating out tool are retained in the arms by which the same is carried. Fig. 8 is a detail showing the manner in which the toolcarrying arm is connected to the movable fulcrum.

Having reference to the drawings, 1 represents a bench or support to which the machine is secured.

2 is the bed-plate of a jack, which may be of well-known form, and which serves to support the shoe on the last while it is being beaten out. The jack shown comprises two uprights, one of which is shown at 3 and between which the bell crank 4 is pivoted at 5. The upper arm of the bell-crank is provided with a pin 6 which projects into a hole in the heel portion of the last. The opposite end of the bell-crank is provided with a spiral spring 7 secured thereto at 8, the lower end of the spring passing down through the supporting bench 1 and being secured at 10 to a screw 9 by means of which the spring may be adjusted if desired. The said screw 9 is set in the bottom of a boX or downward projection 1l from the plate 2. The spring 7 serves to cramp the pin 6 in the hole in the last and also to force the toe of the last down upon the support or upright l2 and so to hold the last firmly in position. The toe-support 12 is provided with a pin 13 in its base and is set on an inclined block or projection 14, the pin 13 being capable of being placed in any one of a series of holes 15 in said block 14, to adjust the ack to accommodate shoes of varying lengths.

The top 120 of the support 12 is pivoted at 121 to the said support and may rock on said pivot thereby permitting the said top 120 to adjust itself to the last. The support 12 is also provided with an adjustable rest 126 which will catch and support the beating out tool in case it slips off the toe of the shoe While the operator is manipulating the said tool. This restcomprises a bent shank portion 128 which passes through a hole in the upright support 12 and is secured therein by means of a set screw 129.. At the upper end of the shank 128 is a head 130, the top of which is preferably covered witha layer of leather 131 or similar soft yielding material.

Beneath the support 1 is bolted or othcrwise firmly secured, a metal plate 16 to which a downwardly and rearwardly projecting arm 17 is secured, preferably the said plate 16 and the arm 17 are cast integral. Near the lower end of the arm 17 two parallel connections or bars 18 are pivoted at 19, the said bars 18 standing in a substantially vertical position, as shown. Two connecting bars 1.8 are employed -parallel with each other for the purpose of affording a space between them through which the curved connection 2() may pass and in which it may be free to operate without interfering in any way with the said connection 18. At`r the same time the connection 20 is permitted to operate in one vertical plane without being offset or bent.

The rear end of the arm 17 is carried upwardly as shown at 175 and forms a rear sto p for the connections 18 to prevent their swinging backwardly too far. A connecting rod 180 is pivoted at its rear end to the bar 18 and at its forward end to the connection 2O as shown, Fig. 1, and serves to prevent undue vibration or swing of the connection 20 when the treadle is suddenly released.

The upper ends of the connecting bars 18 are pivoted at 21 (see Fig. 8) in a box 23 and within the said box 23 the rear end of the forwardly projecting arm or lever 22 is also pivoted by means of a vertical pivot 221. By this arrangement the end of the bar 22 to which the beating-out tool is attached is allowed the longitudinal movement necessary and also a slight sidewise movement in a l'iorizontal plane, which sidewise movement is limited by the sides of the box 28 which serves as a stop therefor. The two pivots 21 and 221 form essentially a universal joint at this point, and within certain limits allow the arm 22 movement in any direction. On the upper edge of the bar 22, about midway of the length thereof, a lug 241 is formed to which is pivoted at 25 the curved connection 20; the said connection' 2() through which the said pivot 25 passes being forked to receive the projection or lug 24.

The connection 20 extends rearwardly, is then curved downwardly, as shown, and passes between the upright connecting bars 18, its lower end being carried forward to a point directly underneath the pivot 25 where it is connected with the treadle connection 26 which extends downwardly to the treadle 27. The latter is located underneath the bench or support of the machine and in convenient proximity to the foot of the operator. As will be clear, when the operator places his foot on the treadle 27 the arm 22 will be forced downwardly and the beating-out tool, which is carried in the head at the forward end of the said arm 22 and is more particularly described below, will be brought into contact with the work, the degree of pressure of the tool upon the work corresponding with the weight or power which the operator applies to the treadle 27. A spiral spring 17() is secured at its upper end to the arm 17 and at its lower end to the treadle 27 and serves to raise the treadle and connectml parts, including the beating-out tool when the operator removes his foot from the treadle.

The forward end of the arm 22 is forked., there being an upper and a lower fork 28 and 2) respectively. Between the two forks 28 and 29 is pivoted a circular supporting-piece 30, the pivots, which are shown at 31 and 32, passing through the arms 28 and 29 respectively, and projecting into sockets in Vl he opposite edges of the circular supporting piece 30, as will be clear from Figs. 1 and 2. By this arrangement of pivots, the supporting piece 8() is permitted to swing in a horizontal plane. The face of the support 3l) is recessed to receive a preferably circular boss 33, the latter being retained in the recess by means of a screw bolt 34 which proj eels through the boss, through the support 3() and is provided at the rear of the support 3() with a nut 35 by means of which the bolt is firmly secured in place. The bolt 341 serves as a pivot upon which the boss and parts supported therefrom, presently to be described, may be swung or moved in a vertical plane. By this arrangement of parts movement in both a horizontal and a vertical plane is obtained.

The boss is provided with arms 3G and 37 which project in opposite directions therefrom and are curved downwardly at their outer ends, as shown F ig. 2, and the arms 3o and 37 are preferably cast integral with the boss. The ends 4of the said arms are forked to form bearings in which are journaled the rods which form the handles of the beatingout tool 38. The said rods are designated 3E) and 390 and are screwed into the ends of the beating out tool and are provided with handles 4() and 41 by means of which the workman may guide and operate the tool. ln Fig. 7 is shown how the luindlc-rods 3l) and 39() are retained in the forked ends of the arms 36 and 87 by retaining prongs 391 which are secured at their upper ends by screws to the said forked arms, the lower ends of said prongs curving around and engaging with the lower or underside of the said rods. By this arrangement the tool and its handles may be readily slipped out of the bearings in the arms 36 and 37 and another tool substituted when that is desired. the beating out tool may be rotatedv on its long axis in the said bearings by means of the handles 40 and 41.

The beating out tool proper, which. i have designated 38, may be provided with. one or As will be clear,

V-two convexly curved faces.

more faces of any required or well-known character or construction. Preferably, I make said tool substantially in the form of a triangular prism having one ilat face and In constructing the same I employ a metal casting of substantially the form above mentioned and shown in Figs. 5 and 6, from which a large section of the central portion has been removed by coring, or by cutting away the same in a plane substantially parallel with the flat surface or face of the prism. The portions so removed, however, should not be -so great but that a considerable amount of metal is left at the apex 420 of the same. Furthermore, enough metal should be left at the ends thereof to afford a firm hold for the handles which are screwed thereinto as is mentioned in a previous part of the speciiication. Into the portion of the tool which has been thus cored out, I insert a block 200 preferably of wood, which is firmly secured therein in any well-known manner. The projecting edges 43 of the wooden block are rounded into a convex form and are smoothed down, sufhcient'material being however, so that the said facin s are entirely outside of and protrude a s ight amount beyond the metal frame. Thus a tool is formed having a flat metal face and two curvedfaces 43 and 44 of wood. The metal apex 420 is sharpened, thus forming a metallic edge which is useful in working down the larger and rougher projections on the sole. The tool is mountedin the arms by which it is carried by means of handles in a manner already described in a previous part of this specification.

As will be clear to those skilled in the art it will frequently be advantageous to cause the beating out tool to reciprocate rapidly while it is being passed over the shoe sole and while at the same time it is exerting a considerable pressure upon the work. This reciprocation may be more conveniently effected by the application of power, and to that end I have provided a special tool frame or carrier for the beating out tool in which the-tool is adapted to be reciprocated by power; which said frame may be substituted for the frame' carrying the tool herein before described designed to be operated only by hand. This modification isshown in Figs. 3 and 4. Referring to the said Figs. 3 and 4, 45 designates a screw-bolt for securing the frame in the head of the machine, which screw-bolt 45 corresponds with the bolt 34 previously described. It will be observed that Figs. 3 and 4 are shown upon a larger scale than the corresponding parts in Figs. 1 and 2. The said bolt 45 serves as a pivot upon which is pivoted and supported a-frame comprising aj horizontal cross-bar 46 projecting on either side of the boss 47, through which the pivot V45dpasses and two vertical end portions 48' 49. These parts together constitute'a4 a shaft 50 upon which is secured a grooved pulley 51 which normally runs loosely upon the shaft. On the said shaft is also a fast pulley 52 provided with a hub or boss lo-. cated between the said fast pulley 52 and the loose pulley 51.

The pulley 52 and its hub or boss is provided with a recess 53 in which is located a pin 54 together with a spiral spring 55 which normally operates to force the pin 54 into a recess formed in the loose pulley 51. The said pin is provided with a block 541, which extends laterally from the same so as to roj ect for a short distance outside of the hu or boss of pulley 52. A slot is cut in thesaid hub or boss so as to permit the movement of the block 541. The free end of the said block 541 is inclined as shown at 542, and is adapted to engage with a coperating shipper lever 56 which is formed with a curved arm 561 lying closely around the hub or boss of pulley 52, and having the extreme end of its curved portion tapered as shown in Fig. 3. The said shipper lever is mounted upon a shaft 57 and is rigidly connected by means of the said shaft 57 with a thumb lever 59. The shaft 57 has a journal or bearing 58 for the same formed in the end of a horizontal projection 60 on the frame-piece 49 as will be clear from Fig. 4. When the shipper lever is thrown away from the hub or pulley 52 and out of engagement with block 541 the pin 53 will be forced by its spring into the recess in the grooved pulley 51 causing the pulley 52 and the shaft 50 to revolve therewith. When, however, it is desired to throw the grooved pulley 51 and the pulley `52 out of engagement, thetapered curved end of the shipper lever is placed near the hub of pulley 52 so asto lie in the path of the appioachng block 541. As the latter engages the tapered end 561 with its inclined face 542 the pin is forced from the recess in pulley 51 into which it has entered and thus throws the same out of engagement with the pulley 52. `Below the thumb lever 59 I provide a rigid projection 61 from the frame piece 49. 'The operator may grasp the projection or arm 61 and by placing his thumb upon the lever 59 throw the shipper out of engagement with the pin 53, thus allowing the pin to be shot into the recess in the loose 'pulley 51, causing the are ivoted on screw studs 64 and 65, respective y which pass through said levers and project into the end pieces 49 and 48 of the frame. The Iupper ends of the levers 62and 63 are yoke-shaped, as shown Fig. 4, and cooperate with eccentrics, which are shown at 66, one being located at each end of shaft 50 and being fast on the same. As the shaft 50 revolves these eccentrics cause the levers 62 and 63 to be reciprocated on their pivots 64 and 65. The lower ends-of said levers are also yoke-shaped and embrace the handles 67 upon which the tool is mounted so that as the levers 62 and 63 are reciprocated they will cause reciprocation of the tool, as will be clear. To permit the tool to reciprocate, the bearings through which the shaft of the tool passes and which are located at the lower ends of the frame pieces 48 and 49 respectively, are elongated as shown at 68, Fig. 4, the length of the bearing or slot being suiiicient to provide for a reci rocation or throw of the tool as great as wil be given it by the eccentrics 66.

The grooved pulley 51 may be connected by means of a driving band or cord 501 with any suitable source of power, not shown. To provide means for taking up the slack of the cord 501 which is caused by pulley 51 partaking in the horizontal or forward and backward movements of the beating out tool, I run said cord 501 over an idler pulley 502 (see Fig. 4) said idler pulley 502 being connected by means of a spring 503 with a fixed point on a suitable fixed support or the like, as shown at 504. Although this means of driving pulley 51 is employed, I do not desire to limit myself to the same.
